thread
broke
The thread having broken with the last weight, of 64 oz,the experiments could not be further prosecuted for the pro-posed velocity, 20 feet. I was therefore obliged to be con-tent with the case of a smaller velocity, as that of 12 feet forexample, which would not require so large an actuatingweight; the results of which are as follow.
